For easier prep, the chicken can be grilled in advance and served chilled or at room temperature on the salad. If you prefer not to use raw egg yolks in the dressing, substitute them with 1/4 cup of mayonnaise and whisk it with the remaining dressing ingredients, thinning with a splash of water or extra lemon juice as needed. Keep the romaine very cold and well dried to maintain maximum crunch, and store all components separately if preparing ahead, assembling just before serving so the lettuce and parmesan crisps stay crisp. This salad is quite rich and filling, so adjust the amount of dressing and cheese to fit your personal macros while keeping net carbs low.
